To aZZfwLom it may concern.'

Be it known that I, JULIUs L. CABELIN- SKY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have Y invented an Improvement in Guards for MachineTables, of which the following is a specification.

In power-driven sewing machines, used in the manufacture of clothing and the like, it is desirable to provide means for shielding the clothing of the operator from the main balance wheel, and it is further desirable, under some conditions, to provide means for inclosing the space beneath the machine table at the rear thereof, to provide a shield for counter-shafting and the like.

The object of my invention is to provide a wheel-guard and an inclosing-means for the space beneath the machine table, which may be readily installed, and which may be as readily removed, when desired.

I accomplish these objects by the means shown in the accompanying drawing, in which Figure 1 is a front elevation of a machine table provided with shielding-means embodying my invention.

Fig. 2 is a cross section on the line 2-2 of Fig. 1.

Fig. 3 is a cross section on the line 3-3 of Fig. 1.

Fig. 4 is a detail view of one end of the wheel guard.

Fig. 5 is a detail sectional view on the line 5 5 of Fig. 1.

In the drawing, a indicates a machine table of common form, having end-supports b, the usual balance wheel c being mounted on the inner side of the right-hand support.

According to my invention, an angle iron al, of Z-form, is provided, one flange of which is secured to the under side of the table, in a position adjacent and parallel to its rear edge, and the other flange of which is Provided with an upturned lip d at its edge, to form a channel or groove. A pair of sheet metal partitions, or guard plates e and f, having hook-shaped, edge anges e, f', at their upper ends, are suspended from the angle iron d, by means of said flanges, which are arranged to interlock with the groove formed by the lower iange of the angle iron d. The flange (f) of one of the plates (f) is formed to overhang the flange of the other plate, so that the one will slide over the other to permit said plates to be Specification of Letters Patent.

telescoped,and permit adjustment according to the space to be inclosed, or according to the portion of the space which it may be desired to inclose. Rearwardly and upwardly-turned hook-shaped flanges e2, f2, ar'e also formed at the lower edges of the plates e and f, one of which is arranged to slide within the other, similarly to the flanges e', f. A pair of channel irons g are secured to the inner sides of the end-supports of the machine, so that the flanged sides face toward each other, and a metal rod h is arranged to be supported in said flanges e2, f2, with its ends projecting beyond the side edges of said plates, into the channels or grooves of said irons g. Said channels are of suiicient width to permit the ends of said rod to slide freely up and down therein, thereby preventing lat-eral swinging movement of the plates, but permitting the rod to be supported at any level therein.

A shield or guard z', for the main drivewheel, having a guard flange 2 at one edge, is provided between the edge of one of the plates (e) and the adjacent end-support of the table. Said shield is arranged to extend from the front edge of the machine table, downward and rearward in front of and beneath the fly-wheel 0, said shield being removably supported on, or suspended from, a screw k, in the front edge of the table, and having an aperture s therein, through which said screw is adapted to pass.

The lower end of said shield is provided with a hook-shaped flange z", in which the portion of the rod t, opposite said shield is adapted to lie and be supported, the relative arrangement being such that the weight of the rod will be carried partly by the shield z'.

With the above-described construction, in ordinary use, the weight of the rod h holds the plates e, f, and shield z' down firmly against their respective supports, so that the jar and vibration of the machine, when operated, will not cause them to rattle.

It frequently becomes necessary to secure access to the fly-wheel of the machine and to the countershafting in the rear of the plates e and 7". In such case, it is merely necessary to lift the plates, so as to unhook them from the angle iron d, and to disengage the shield z' from its support in like manner, and then disengage them from the rod 71..

The shielding-means may then be readily removed without necessitating the removal of bolts, screws, or other fastening-means,

taken down, and set up again.

I claim l. A guard for machine tables comprising a hook-shaped support disposed beneath the table, a pair of guardplates having hook shaped flanges at their upper and lower ends,the ianges of one plate beingvarranged to slide' on'the flanges of the other,` and said plates being Asuspended from said support by their upper iianges, a rod supported in the lower flanges of said plates and extending beyond their `opposite edges, and'vertically-disposedV guides for the projecting endsA of said rod. Y

2. AA guard for machine tables comprisin a hook-shaped support arranged to extend longitudinally of the table, at its under side, and adjacent its rear Aedge, a guard-plate havingNtransverse, hook-shaped flanges at itsupper 'and'lower ends and suspended by. i

its upper flange from said support, a rod supported in the lower {iange ofl saidV plate and projecting beyond the sides thereof, `lyerticallyedisposed'lguides for the projecting endsof said rod, and a Wheel-guard removably supported a'tfits'lup erelid betweenone edgeof Ysaid plate vand theadjacenti'guide, and having a hook-shapedange at'ts *lov'ver end Aarrangednto "rece'iV-,e'and 's'l'lp'po'i-"tthey adjacent portion of 'said rod.' j
